CQNCEALED-STOP HINGE.

Application filed January 1, 1923.

To all whom it may concern:

Be it known that I, DUDLEY S. VVARTH, a citizen of the United States,and a resident of the borough of Brooklyn, Kings County, city and Stateof New York, have invented an Improvement in Concealed-Stop Hinges, ofwhich the following is a specification.

My present invention relates to hinges for the seats of water-closetsand the like.

which hinges are provided with concealed stops, and aims to providedevices of the character described which shall be simple inconstruction, little liable to get out of order and require repair,which shall have smooth exterior surfaces and thus be adapted to bereadilycleaned, andwvhich shall prevent the seat from striking the flushtank, the flush pipe, the flush valve, or the wall or other objectadjacent to which the seat may be mounted.

.In the accompanying specification I' shall describe, and in the annexeddrawing show, several illustrative embodiments of the present invention.It is, however, to be clearly understood" that my present inventionisnot limited to the particular embodiments thereof which are hereinshown and described for purposes of illustration only. i

Referring to the drawings, in which the aforesaid illustrativeembodiments of the present invention are shown 2 Fig. 1 shows a planview, partly broken away, of one of the aforesaid illustrativeembodiments of the present invention as ap plied more particularly to adivided watercloset seat;

Fig. 10 is a cross-sectional view of the hinge post shown in Fig. 9.

Before describing in detail the aforesaid illustrative embodiments ofthe present in vention, it may be desirable briefly to point out thedisadvantages of the devices used in the prior art for accomplishing thesame general results intended to be accomplished by the devices of thepresent invention. As far as I am aware, all of the stop hingeshithertoemployed or suggested for use in connection with water-closetseats and like devices have had embodied therein external visibleattachments which are cumbersome, which render such hinges expensive tomanufacture and difficult to attach, which are very liable to get out oforder and to requirev pose, are obtained in a simple but highlyingenious manner. a

Referring first to the illustrative embodiment of the present inventionshown in Figs. 1, 2, 3 and 4: of the drawing, S indicates a videdconstruction type. comprising the two members 10 and 11. The members 10and 11 are held together in properspaced relation with respect to eachother by means of the hinge generally designated by reference characterH.

In the illustrative form now being described, thehinge H comprises a bar19. having attaching plates 13 and 1t in the form of fins or extensionswhich are attached to the respective seat members 10 and 11 by means ofthe screws or other suitable fastening devices 15.

As a part of my present invention I provide concealed means for limitingthe angle through which the seat can be rotated in at least onedirection, as in an upward direction, but preferably in both directions,that is in both the horizontal and raised positions of the seat, so thatthe same will be stopped and maintained in the desired position orpositions by means concealed within the hinge structure itself.

For this purpose I provide the bar 12 with the pintles 16 at each end ofthe same. Preferably, the pintles 16 are integral with the bar 12, asare also the fins or attaching plates 13 and 1 1-, so that the bar 12,the fins or attaching plates 13 and 14, and the pintles 16, may be castin a single piece.

In the illustrative form now being described, each pintle 16 is ofsubstantially circular cross-section adjacent its inner end 17, where itjoins the rod 12, and has a re-' duced end portion 18 which ispreferably of semi-circular cross-section.

Cooperating with the pintles 16 are a plurality of hinge posts 19 havingthe threaded rods 20 adapted to pass through the porcelain, of the bowland to be held in position in the bowl by any suitable fastening means,such as nuts and washers, or the like, not here deemed necessary to beshown, in the manner well-known to those skilled in the art to which thepresent invention relates.

The upper portion of each hinge post 19 comprises a flange 21 and a head22 provided with a transverse socket The socket 23 contains concealedtherein means cooperating with the pintles or other equivalent remainingportions of the hinge structure for limiting the angle through which theseat can be turned in either direction, up or down, corresponding to thehorizontal and raised positions of the water-closet seat, respectively.For this purpose the socket 23 is of substantially circularcross-section adjacent the outer portion 24 thereof, corresponding tothe substantially circular cross-section of the pintles 16 adjacent theinner end 17 thereof. Adjacent its inner end 25, the socket 23 is ofreduced crosssection, as in the form of a reentrant angle. For thispurpose the socket 23 is provided with a boss or projection 26 extendingfrom the base 27 part way towards the outer surface 28 of. the head 22of the hinge post 19, as more clearly shown in Figs. 3 and t of thedrawing.

The manner of assembling the device comprising the aforesaidillustrative embodiment of the present invention, and the man ner ofoperating the same, together with the advantages of the same inoperation, will be substantially clear from the foregoing descriptionand may be briefly summarized as follows: After the attaching plates orfins 13 and 1 1 of the bar 12 forming a part of the hinge H have beenattached to the members 10 and 11 of the seat S by any suitable means,as by means of the screws or other suitable fastening devices 15, thehinge posts 19 are applied to the pintles 16 by bringing the sockets 23of the hinge posts 19 over the respective reduced end portions 18 of thepintles 16. By means of the threaded rods 20 and the associatedfastening means such as the nuts and washers or the like, which it isnot deemed necessary to show here, the hinge posts 19 carrying the seatS are positioned and fixed in the porcelain of the water-closet or likedevice.

In operation, it will be noted that the seat S may be rotated intoraised position due to the bearing of the pintles 16 in the sockets 28of the hinge posts 19. The maximum upward swing of the seat S is limitedand determined by the angle of the front face of the boss or otherraised portion 26. The front face of the reduced end portion 18 of eachof the pintles 17 serves as a stop or limit for the angle through whichthe seat S can be rotated into raised or open position. In the same way,the angle through which the seat S can be rotated into horizontal orclosed position is determined by the engagement between the lower faceof the boss or projection 26 and the flat face of the reduced endportion 18.

It will be noted that I have provided, in an exceedingly simple andeconomical. type of construction, a concealed stop hinge which is littleliable to get out of order and require repair, which has smooth exteriorsurfaces and is thus adapted to be readily cleaned, and which preventsthe seat from striking the flush tank, the flush pipe, the flush Valve,and the wall or other object adj acent to which the seat may be mounted.

It will be noted that all ofthese desirable results are accomplishedwithout the ezn ployment of any external or visible attaching meanswhich are crunbersome, which render such hinges as? ordinarily madeexpensive to manufacture and diilicul t to at tach, and which are veryliable to get out of order and to require repair and replacement. Thehinges formerly made for the same purpose are difficult to clean and tokeep clean and generally present an unattractive appearance quitedifferent from the neat and attractive appearance presented by theaforesaid illustrative embodin'ient of the present invention.

Turning now to the illustrative embodiment of the present inventionshown in Figs. 5, 6, 7, 8, 9 and 10 of the drawing, S designates thewater-closet seat which is in this case of the one-piece type ofconstruction. Suitably attached to the seat S, as by means of thethreaded bolts 30 more clearly shown in Fig. of the drawing, are aplurality of pintle posts 31 each consisting of the head portion or knob32 and the pintles 33 extending transversely of the knob or head portion32 of the pintle post 31.

Each pintle 33, like the pintle 16 of the embodiment ofthe presentinvention described in the earlier portion of this specification, is ofsubstantially circular cross section adjacent its inner end 34, where itjoins the knob or head portion 32- of the pintle post 31, and has areduced end portion 35 which is preferably of semi-circular crosssection.

Cooperating with the pintles 33 are a plurality of hinge posts 36 havingthe threaded rods 37 adapted to pass'through the porcelain of the bowland to be held in position in the bowl by any suitable fastening means,such as nuts and washers, or the like, not here deemed necessaryto. beshown, in the manner well known to those skilled in the art to which thepresent invention relates.

The upper portion of each hinge post 36 comprises a flange 38 and a head39 provided with the transverse socket 40. The socket l0 containsconcealed therein means cooperating with the pintles or other equivalentremaining portions of the hinge structure for limiting the angle throughwhich the seat can be turned in either direction, up or down,corresponding to the horizontal and raised portions of the water-closetseat, respectively. For this purpose the socket 40 is of substantiallycircular cross section adjacent the outer portion ll thereof,corresponding to the substantially circular cross section of the pintles33 adjacent the inner end 34 thereof. 7 Adjacent its inner end 42, thesocket 40 is of reduced cross section, as in the form of a reentrantangle. For this purpose the socket 40 is provided with a boss orprojection 43 extending from the base 44 part way towards the outersurface 45 of the head 39 of the hinge post 36, as more clearly shown inFigs. 9 and of the drawing.

The manner of assembling the device comprising the aforesaidillustrative embodiment of the present invention, and the manner ofoperating the same, together with the advantages of the same inoperation, will be substantially clear from the foregoing descriptionand may be briefly summarized as follows: The pintle posts are firstattached in suitable positions to the seat S by any suitable fasteningmeans, as by means of the threaded posts 31. The sockets 40 of the hingeposts 36 are now applied over the reduced end portions of the pintles33, in a manner that will be clear to those skilled in the art to whichthe present invention relates. The threaded posts 37 are now applied tothe porcelain of the bowl andare held in position therein by anysuitable fastening means, such as nuts and washers, or the like, nothere deemed necessary to be shown.-

In the operation of the aforesaid illustrative embodiment of the presentinvention, the seat S may be rotated into raised or upward position bymeans of the pintles 33 bearing within the sockets of the hinge posts36. The angle through which the seat S may be rotated into raised orupward position is limited and determined by the engagement of the flatface of the reduced end portion 35 of the pintle 33 with the inclinedfront face of the boss or projection 43 within the socket 40. Similarly,the angle through which the seat S can be rotated into horizontal orclosed position will be limited and determined by the engagement of theflat face of the reduced end portion 35 of the pintle 33 with the loweror horizontal face of the boss or projection 43 of the socket 40.

It will be noted that in this way I provide a concealed stop hinge forthe seats of waterclosets and the like which possesses all of theadvantages numerated above in connection with the illustrativeembodiment of the present invention described in the earlier portions ofthis specification, and which possesses none of the disadvantagesinherent in the devices employed or suggested for use, as constructed inaccordance with the methods hitherto employed in the prior art. Thedevice is exceedingly simple and cheap in construction, is little liableto get out of order and require repair or replacement, has a smoothexterior surface and is thus adapted to be readily cleaned, and is soarranged as to prevent the seat from striking the flush tank, the flushpipe, the flush valve or the wall or other object adjacent to which theseat may be mounted. At the same time I provide concealed means forlimiting the rotation of the seat in either direction, upward ordownward, while avoiding the disadvantages inherent in the stops forhinges hitherto employed or suggested for use in connection with theseats of water-closets and the like.

WVhat I claim is:

1. In a concealed stop hinge for the seats of water-closets and thelike, a pintle having a substantially circular bearing surface and areduced end portion of substantially semicircular cross-section.

2. In a concealed stop hinge for the seats of water-closets and thelike, a cross bar having at each end thereof a bearing pintle ofsubstantially circular cross-section having a reduced end portion ofsubstantially semi-circular cross-section. I

In a concealed stop hinge for theseats of waterclosets and thelike,-a hinge post having a socket of substantiallycircularcross-section adjacent the outer end thereof and substantiallyof a reentrant angle crosssection adjacent the inner end thereof, incombination with a pin'tle of substantially circular cross-sectionhaving a reduced end portion of substantially sen'ii-cir'cularcrosssection.

5. In a concealed stop hinge for the seats of water-closets and thelike, a plurality of reduced end portion of substantially semicircularcross-section.

(3. In a concealed stop hinge for the seats of water closets andthe'like, a pintle having a'be'aring'por'tion and reduced end portion,-ahinge post having a socket for re- 7. In a concealed stop hinge for theseats of Water-closets and'the like, a p'intle havinga reduced endportion, a hinge post having a socket for receiving the pintle and theend of said pintle, and means concealed Within said socket andcooperating with said end portion for limiting the angle of rotationof'said pintle in both directions;

In testimony, whereof, I have signed' my name to this specification this(3th day of December, 1922.

DUDLEY S. IVARTH.
